A LABOUR government would impose tough restrictions on the sale and advertising of alcohol, unhealthy food and tobacco, according to a leaked policy document.

The plan would end sports sponsorship by drinks firms and impose minimum alcohol pricing in an effort to cut the impact of drinking on Britons' health.

There would also be new laws to curb the amount of sugar, fat and salt in food aimed at children, and a ban on advertising unhealthy products on TV before the 9pm watershed.

The Mail on Sunday reported that the plans are contained in a report to the "society" sub-group of the shadow cabinet.

Setting out the reasons for the clampdown on alcohol, the Labour document says: 'Up to 35 per cent of all A&E attendances and ambulance costs may be alcohol related and up to 70 per cent at weekend peak times."

However, it has been claimed that Miliband has faced a backlash from members of his party over the plans.

One Labour MP said: "Issuing diktats on eating and drinking and strangling supermarkets and drinks companies with more regulations is a return to the failed Old Labour approach.

"We need to show business we are on their side – and stop meddling in every aspect of people’s lives."

The plan includes an end to drinks firms sponsoring sporting events by 2020.

It is estimated that a ban on all sponsorship by drinks companies would cost the sporting world £300 million a year, affect 11 Premiership football teams and spell the end for Budweiser's sponsorship of the FA Cup, Heineken's branding of the European Cup rugby tournament and Crabbie's support of the Grand National.

The proposals also include introducing a minimum price for alcohol and restrictions on where drink could be sold in supermarkets.

There measures to tackle smoking are also included, with the intention that "children born in 2015 will become the first smoke-free generation for hundreds of years."

The plan would involve a ban on smoking in cars with children present - a measure that has already been backed by MPs - and the introduction of plain packaging.

The newspaper said measures to combat obesity could result in a ban on some high-sugar breakfast cereals and an end to sweets at the supermarket checkout.

A Labour spokesman said the leaked paper "represents a wide range of options" but was not official party policy.

He said: "Improving public health is crucial to people's quality of life. That's why we've rightly pressed the Government to end their opposition to plain cigarette packaging."

Conservative Party chairman Grant Shapps said: "It's the same old Labour. They claim they're worried about prices - but want to put up the cost of a drink. Not only would that make a drink after work more expensive, it would hit pubs hard, putting many out of business.

"It's becoming clearer every day that Ed Miliband just offers more of the same old Labour, and no economic plan to secure Britain's future."
